ABSTRACTIndonesia has an abundant quantity of natural zeolites that have not yet been utilized maximally. On the other hand, fishpond farmers have a problem regarding the presence of ammonium in the fishpond water which will negatively impact to survival of fish, especially small fish. To solve this problem, this research was utilizing natural zeolite to degrade ammonium in the fishpond water. This research aimed to test mordenite natural zeolite from Bayah as an adsorbent to collaborate some variables impact to reach more maximal adsorption. The variables that were used to be observed were: mordenite natural zeolite from Bayah as an adsorbent which has been activated by 1-7 N H2SO4 and the other was without activation, ammonium concentration of 80-800 ppm, the particle size of adsorbent of 80 and 150 mesh, stirring speed of 600 and 800 rpm, and without stirring by duration adsorption time of 60 minutes. The research results showed that mordenite natural zeolite after activated was able to adsorb of 100% ammonium, while for the mordenite natural zeolite from Bayah without stirring was of 80%, by the same absorption time. These results will give significant benefits for fishpond farmers to increase their productivity because of the increase in fish survival.Keywords: adsorption, adsorbent, zeolite, amoniumABSTRAKKandungan zeolit alam di Indonesia cukup melimpah dan belum termanfaatkan secara maksimal.

Tujuan penelitian ini adalah untuk menganalisis bagaimana ibu rumah tangga yang bekerja sebagai tukang amplas kerajinan ukir kayu menjalankan peranannya dalam rumah tangga dan bagaimana peran mereka dalam industri kerajinan ukir kayu di Desa Keling Kecamatan Keling Kabupaten Jepara.  Berdasarkan hasil penelitian dapat dilihat ibu-ibu tukang amplas mempunyai peran penting sebagai “penyempurna produk” dalam industri kerajinan ukir kayu. Namun disisi lain sebagai ibu rumah tangga, mereka tidak dapat melepaskan tanggung jawab sosial budaya sebagai “pengurus rumah tangga”. Dengan demikian pekerjaan mengurusi rumah, melayani suami dan anak – anak tetap mereka lakukan bersamaan dengan peran mereka sebagai pekerja tukang amplas. Peran ganda yang mereka jalani tersebut membawa dampak secara sosial mereka memiliki prestise lebih dibanding ibu yang tidak bekerja, namun disisi lain peran ganda tersebut menyebabkan para ibu rumah tangga tukang amplas tersebut menjadi terbebani baik dari segi waktu maupun tenaga mereka.The purpose of this study is to analyze the domestic burden of a housewife who worked as a wood carving craft sandpaper and the role they play in handicraft industry. The research is conducted in Keling, Jepara. The research results show that these women have important role  in wood carving handicraft industry as ”product perfector” and in their house hold as ”domestic manager”. As a housewife, they can not leave their domestic responsibilities regarded by society as their main tasks. Consequently, they have double tasks, serving her husband and children  in the house as well as performing their roles as labours. This dual role gives them more prestige than women who do not work, but on the other hand this dual role also give them double burden.

Volunteering is an activity that enables the development of an individual’s competency and is also an area of interest both of society and the academic community. This article aims to compare the motivation for volunteering and the experience of volunteering with students within helping professions and economics. For the purpose of this research, a questionnaire about volunteering was compiled. The article presents the research results into volunteering of Czech students of economic and non-economic study programmes of the College of Polytechnics Jihlava (n = 282). According to the results, the field of study and the frequency of volunteering depend on each other. Students’ gender and the frequency of volunteering do not depend on each other; neither do the study field and the volunteering experience. The biggest motivations for volunteering are feeling useful, gaining new experience and skills. On the other hand, the lack of time and information (ignorance) are perceived as limitations. The study provides an opportunity for developing more guidelines in promoting volunteering activities within the young population and society as a whole.

This research is based on the testing of the impact of the board (particleboard and medium density fiberboard (MDF)) and hardware type used to connect the sides and the bottom or top of the storage furniture on the joint strength. The hardwares of the following trade mark were used: the confirmat screw, Minifix, Maxifix, Stablofix, RV and Solo 32. Such hardwares make it possible to disassemble the furniture as well as to assemble it (when moving the furniture) without reducing joint strength when reassembling it due to wear and tear on the material (with the exception of the confirmant screw). Research results showed that assemblies with the Maxifix hardware installed in the MDF base exhibited the highest values of bending moment (the average bending moment of 85.88 Nm). On the other hand, assemblies with the Minifix hardware installed in the particleboard exhibited the lowest values of bending moment (over three times lower than the Maxifix) (the average bending moment of 24.50 Nm). Assemblies with the confirmat screw exhibited satisfactory results, although, aesthetic requirements seem to be the main problem here (the average bending moment of 40.38 Nm for the particleboard and of 64.24 Nm for the MDF).

The research studied enhanced treatment of sewage from discharging points of rivers by biofilm process dosing with enzyme and promotion effect of enzyme on treatment of sewage by biofilm process, and investigated the changes of removal rates of the main pollution indexes at different temperature to ensure the optimal temperature. The research results indicated that temperature was an important factor influencing the removal rates of the main pollution indexes. When temperature was in the range of 5°C-8°C, the promotion effects of enzyme on the removals of CODCrand ammonia nitrogen (NH3-N) of sewage by biofilm process were not obvious. However when temperature were in the ranges of 15°C -18°C and 22°C -25°C, enzyme had the high promotion effects on the removals of the pollution indexes. Furthermore, within the certain temperature (5°C -25°C), the removal rates of CODCrand NH3-N were on the rise with the increase of temperature. When temperature increased from 5°C -8°C to 15°C -18°C, the removal rate of CODCrobviously increased, but when temperature continued to increase to 25, the rise trend of the removal rate of CODCrbecame slow. On the other hand, when temperature increased from 5°C -8°C to 22°C -25°C, the increase of the removal rate of NH3-N was always evident. Therefore, the optimal temperature was in the range of 22°C -25°C for the enhanced treatment of sewage from discharging points of rivers by biofilm process dosing with enzyme.
